Wire nut capacity?

footwedgeApril 19, 2011

I purchased Ideal red wing twist wire nuts, 600V max. On the package it states a max of 5 #12. I have not seen this anywhere else.

If it has a max of 5 #12 will it hold 6 #14s or should I splice 3 and 3 with a jumper between the two wire nuts? or just add another jb?

I have 6 14-2 cables coming into a junction box. The lead in terminates at the box but I need to branch off to 3 switches and 2 low voltage power supplies all at different locations. This is part of a kitchen remodel and I'm trying to reduce the amount of dry wall. The calculated load on this circuit is 9 amps.

Any suggestions

It should say more than just "5 - #12". It should give you a range of options.

Take a look at the chart but the way I'm reading it, the red Ideal "Wing Nut" #452 is approved for 1 to 6 #14 wires.

Here is a link that might be useful: Ideal UL Listed Combinations

According to the package "min 2 #14 - max 5 #12".

The model number is WT52.

Thanks Mike, the link shows 5 #14s and 1 #18. I guess I will use the jumper, if it is allowed by the code.

Pigtails are fine.

Every wire nbut has a range of combinations in can be used on, based on the total circular mils of the wires.

The box should have many of the combinations, but the listing sheet will will ALL the combinations.

WT52 = 2 to 6 #14.

With the preceding link, look at the fourth column, third listing from the bottom of that column.

Thanks again Mike. I need to slow down. Even though it states 6 which would be the max, what would the experts recommend: using the jumpers or nutting the max (6)?

Professionals would never use jumpers like that. That screams diy/handyman/etc.
We would use the proper size wire nut, even if that means reaching in our pouch and using a grey or big blue.

So Petey, do you max out a wire nut or do you always stay below the max rec # of wires by going up in wire nut size?

As you can tell, I prefer insurance except when it costs to much.

I try not to have that many wires under a wired nut regardless.
For any box in a typical 15 or 20A circuit 5-6 wires should be the most you'd ever need to put under a wire nut.
